| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | Fiber nonlinearity has become a major limiting factor to realize ultra-high-speed optical communications. We propose a fractionally-spaced equalizer which exploits trained multivariate high-order statistics (mean, variance, skewness, etc.) to deal with data-pattern dependent nonlinear impairment in fiber optic communications. The computer simulation reveals that the proposed 3-tap equalizer improves Q-factor by more than 2dB for long-haul transmissions of 5,230km and 40Gbps. We also demonstrate that the joint use of a digital backpropagation (DBP) and the proposed equalizer offers an additional 1-2dB performance improvement due to the channel shortening gain. | |
